LAMP-WICK.

SPECIFICATION forming part of Letters Patent No. 463,961, dated November 24, 1891.

Application filed November 29,1890. Serial No. 373.062. (No model.)

To all whom t may concern:

Be it known that I, RUSSELL I). AMBLER, a citizen of the United States, and a resident of De Funiak Springs,in the county of Walton and State of Florida, have invented oert-ain new and useful Improvements in Lamp- Wicks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical section. Fig. 2 is a detail view showing the case.

This invention relates to non-combustible wicks for kerosene-lamp burners; and it consists in the novel combination and arrangement of parts as hereinafter set forth.

The object of the invention is to provide for lamp-burners a wick which shall be stationary within its chamber and practically indestructible.

In the use of ordinary .wicks which are raised and lowered to regulate the flame it is difficult to trim them so that the flame will be even, smoke being thereby produced on account of the inequalities. It is also difficult to raise the old style of wick by a true line, so that one part will not be higher than another, particularly when they are very broad.

The present invention is designed to obviate such disadvantages by construct-ing the wick of incombustible material, and so arranging it that no trimming will be necessary, a smooth and even surface being always presented at the point of combustion. The flame will be regulated by means not herein described.

To accomplish the object of this invention the lower part of the wick-chamber A is filled with common wicking or its equivalent, leaving a space b near the top of about one-half an inch or more in depth. Within the space h is introduced my composite wick, consisting of a removable wiregauze shell or case B, which is of the general contour of the said space b, and projecting about one-quarter of 5o an inch yabove the edges of the latter, said gauze shell being filled with a compound of equal parts of bone-black and graphite intimately mixed and packed therein level with the upper edges of the said shell. These united substances have three importantusesviz'., to convey the oil from the common wicking to the Iiame, to prevent ignition and consequent waste of' its own particles, and to avoid the tendency to incrustation which exists in most substances or compounds when brought in contact with burning oil. This casing, in addition to holding the mixed material in place, serves to admit air through its small interstices to unite with the flame at the point where combustion begins and increase the power of the flame. That such an effect is produced is demonstrated by the fact that when a solid case of metalis substituted for the wire-cloth the iiame is immediately reduced. It will be observed, therefore, that the mixture above referred to, in connection with the wire casing or shell, produces the effect of a common wick without the disadvantages of the latter.

I am aware that it is not new to provide lamp-wicks with a tip of netting containing refractory material, and I do not therefore claim the idea broadly; but

.What I claim, and desire to secure byfLetters Patent, is-

1. Acomposite tip for wicking, formed of a mixture of equalparts of bone-black and graphite, substantially as specified.

2. The combination, with the Wick-chamber of a lamp having a common wicking therein terminating a short distance below the upper end. thereof, of a composite wick formed of equal parts of bone-black and graphite inclosed in an open-work shell or covering of wire-gauze, said composite wick placed in the wick-tube above the common wicking and in contact therewith, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

RUSSELL P. AMBLER.
